Sea level is one of the most useful oceanographic parameters. Sea level data are vital to scientists for studies of fluctuations in major ocean currents and global climate change, to engineers for the design of coastal installations, to a large community engaged in what is now called 'operational oceanography' (e.g. the provision of flood warnings from storm surges and tsunamis), and in local applications such as provision of tide tables and real-time data for port operations. For nearly 25 years, the Global Sea Level Observing System (GLOSS) has provided oversight for the operation of tide gauge networks and has ensured that requirements for accuracy, frequency and latency of sea level data are met for a broad base of users. After a brief background of the program, we present a status report of GLOSS in 2009, and provide community recommendations for the future role of GLOSS in the coming decade.
